Leeds prop Ryan Bailey has been given a one-match ban for punching and will have to miss the final game of the regular Super League season.
The Rugby Football League's disciplinary committee also handed Bailey a £300 fine for the punch, which took place during the 20-12 victory over Catalan Dragons.
Bailey, who had just returned to action against the Dragons following a 12-week absence with a hand injury, will sit out Thursday's trip to Wigan but will be available for the first round of the play-offs, in which the Rhinos will face either Warrington or Huddersfield.
His absence for Thursday's match could be offset by the returns of forwards Jamie Jones-Buchanan and Brett Delaney, who have both been named in Brian McDermott's 19-man squad.
And hooker Rob Burrow may also be back after missing the Dragons match due to a back injury.
